Shopify Reviews & Trust: Building Social Proof Under German Law

Shopify reviews are the strongest trust signal for new stores, and at the same time a popular trap for warning letters (Abmahnungen) in Germany. Here you'll learn which trust elements really count, how to add reviews to Shopify, which mandatory disclosures have applied since 2022, and how to collect genuine reviews without the risk of a warning letter. This article is part of our overview Shopify marketing: how to get your first sales.

Which trust elements really count

Trust doesn't come from seal graphics but from the information a cautious buyer looks for. In a survey of US online shoppers by the Baymard Institute, 19% named lack of trust in entering payment details as a reason for abandoning a purchase. These elements make the difference:

You'll find the mandatory information in detail in the article protecting your Shopify store against warning letters. Faulty legal texts hurt trust twice: attentive customers notice them, and competitors send warning letters over them.

Adding Shopify reviews: which app?

Shopify's former free app "Product Reviews" was discontinued in May 2024. Today you need a third-party app. The first important distinction:

• Product reviews relate to an item and appear on the product page.
• Store reviews relate to you as a merchant: delivery, service, communication. They fit on the homepage, in the footer and near checkout.

There are many other apps as well, such as Loox or Yotpo. When choosing, look for three things: labeling of verified buyers, the option to show the authenticity notice directly on the widget, and a review section for the homepage. The latter is handy if you sell one-off items and each product page would only have one review. For pure store reviews, Trustpilot is also widespread. The authenticity notice also applies to reviews collected there as soon as you show them in your store.

App installed, but no stars on the product page?

The app alone isn't enough; you have to place its blocks in the theme. Open the theme editor, switch to the "Products" template at the top and add the app's block, usually one for the stars below the title and a section for the reviews further down. Current themes such as Dawn or Horizon support such app blocks. With older or heavily modified premium themes, this sometimes doesn't work; then the app's support or a code snippet helps. You can program a review feature without any app, but then you have to build the form, moderation and authenticity checks yourself. When something like that pays off is covered in the article customizing Shopify code.

Which other apps are worth it at the start is covered in our overview Shopify apps for beginners.

Mandatory disclosure: are the reviews checked?

If you show customer reviews, you must state whether and how you ensure that they come from consumers who actually bought or used the product. This is governed by § 5b(3) UWG (German Act Against Unfair Competition), in force since 28 May 2022. If this information is missing, it counts as withholding material information, and you risk a warning letter.

The obligation doesn't only apply to checked reviews. If you don't check, you may still show the reviews, but you have to say exactly that openly (IT-Recht Kanzlei (German)).

Where the notice has to be

The notice belongs in the immediate vicinity of the reviews, i.e. directly on the review widget or as a clearly visible link there. In May 2026, the Higher Regional Court (OLG) of Frankfurt ruled that a notice behind an expandable section called "Competition law notices" is not enough, because nobody expects information about review checks there (decision of 19 May 2026, ref. 6 U 305/25, report on onlinemarktplatz.de (German)). The Regional Court (LG) of Deggendorf also ruled against a store in March 2026 over a missing authenticity notice (judgment of 27 March 2026, ref. 1 HK O 6/25, not final, appeal pending at the OLG Munich, report by IT-Recht Kanzlei (German)).

This also applies to embedded reviews from platforms like Google. If you show them on your own site, you are responsible for the notice.

Example wording

These examples are starting points, not finished legal texts. They must match your actual process exactly.

If you check: "Information on the authenticity of reviews: Only customers who bought the product from us can leave a review. For this purpose, we send an invitation linked to the order after delivery. These reviews are labeled 'Verified purchase'."

If you don't check: "Information on the authenticity of reviews: We do not check whether the reviews come from people who bought or used the product."

Never claim more than you do. Writing "only verified reviews" when the form is open to anyone makes things worse than having no notice at all.

What is prohibited: fake, purchased, imported

The "blacklist" in the annex to the UWG prohibits certain practices with no ifs or buts:

• No. 23b: Claiming that reviews come from real buyers without taking reasonable and proportionate steps to check this.
• No. 23c: Submitting or commissioning fake reviews, and misrepresenting reviews on social media to promote sales.

You'll find the wording in the annex to the UWG (German). What this means in practice:

• Self-written reviews: prohibited. Also from friends who never had the product.
• Purchased reviews: prohibited, whether via an agency or a review service.
• Importing reviews from AliExpress, CJ or Amazon: We clearly advise against this. These reviews relate to a different merchant, different shipping and often a different product. If they look like reviews from your customers in your store, that's misleading. The fact that some apps offer imports doesn't make them legally safe.
• Hiding negative reviews: Showing only the good ones without an objective reason creates a false overall picture. You may delete what is offensive, spam or obviously unrelated to the product. It's best to set these rules down in writing.
• Fake sales notifications: Pop-ups like "Lisa from Hamburg just bought" that aren't based on real orders are also misleading.

Sample reviews from themes or AI builders

Many themes, templates and AI store builders fill sections like "What our customers say" with placeholders: invented names like "Sarah K.", stars and praise, often the same on every product page. These texts are not reviews but demo content. If they stay in the live store, they look like real customer testimonials, and that is exactly what No. 23c prohibits. Delete such sections before launch or hide them until you have real reviews. Rewriting them into "more realistic" texts doesn't make it any better.

A freshly created product with hundreds of five-star reviews is therefore not a trick but a risk. On the subject of third-party images and content from suppliers, also read product images and trademarks in your store.

Collecting genuine reviews without the risk of a warning letter

Most satisfied customers don't leave a review on their own. You have to ask, but the right way.

The review request by email

A request for a review by email is advertising. Germany's Federal Court of Justice (BGH) ruled this in 2018, even for a request contained in an invoice email (BGH, judgment of 10 July 2018, VI ZR 225/17 (German)). So you need a legal basis:

• Consent: The safest option. For example via a checkbox at checkout that is not pre-ticked and also mentions review requests, with double opt-in.
• Existing-customer exception (§ 7(3) UWG): Only if all requirements are met, in particular a clear notice of the right to object when collecting the address and in every email. In the BGH case, exactly this notice was missing. Whether a review request counts as advertising for "similar goods" under the exception at all has not been conclusively settled. With consent, you're on the safe side.

How to set up consent and double opt-in in Shopify is covered in the article on email marketing in Shopify.

Other ways without email advertising

• Insert in the parcel: A card with a QR code to the review page is not email advertising. For many small stores, this is the simplest way.
• Review link on the order status page: Customers see it when they track their delivery.
• Ask personally: If a customer writes to you on their own to say they're happy, you may ask them for a review in your reply.

Can I give a discount for reviews?

A small incentive is possible if it applies to every honest review, not just positive ones, and if the resulting reviews are clearly labeled. A reward only for five stars is not permitted. The same applies to a prize draw, such as a voucher among all reviewers: it must apply equally to critical reviews, and as a prize draw you need clear terms of participation. If in doubt, leave out the incentive and put the request front and center.

Customer testimonials that you don't get through the app, for example from an email or an Instagram message, may only be published with the person's permission. Ask explicitly whether you may show the text and first name in the store, and keep the consent on file.

Trust without reviews: how to start as a new store

A new store has zero reviews, and that's fine. Don't replace them with fakes, but with other genuine evidence:

• Show yourself. A photo of you or your team and two sentences on why the store exists have a stronger effect than a generic seal.
• Show the real product. Your own photos and short videos, phone footage is fine, instead of only supplier images.
• Product testers: Give the product to real people from your target group and ask for an honest opinion. Label reviews on this basis as "received a free test product".
• User-generated content (UGC): You may show photos that customers post on Instagram or TikTok in your store with their permission. How to get such content is covered in the article first sales without an ad budget.
• Honest delivery times and returns information right on the product page. Uncertainty costs more trust than a long delivery time. You'll find more elements for the product page under optimizing your product page.

Don't advertise things that are a given anyway, such as a "14-day right of return", as a special benefit. The right of withdrawal applies anyway, and presenting it as something special is not permitted under the UWG. You may of course mention it factually.

FAQ

May I import reviews from AliExpress or CJ Dropshipping into my store?

We advise against it. The reviews don't come from your customers, relate to a different merchant and often to different delivery conditions. If they look like reviews of your store, that's misleading and can draw a warning letter. The fact that apps technically offer the import changes nothing. It's better to collect a few genuine reviews.

Do I need trust badges or seals for customers to buy?

No. Home-made badges like "100% secure" do little and can be misleading. A genuine seal such as Trusted Shops can help, but costs money every month. For new stores, a complete imprint, familiar payment methods and clear shipping information often work just as well. Many themes show the logos of your payment methods in the footer via a setting in the theme editor, and only for payment methods that are actually active in the store. If they're missing, check these two points first.

Is the free legal text generator from Trusted Shops an alternative to the trust seal?

These are two different things. The trust seal with buyer protection and reviews is a paid trust element. Free legal text generators, including the one from Trusted Shops, provide your terms and conditions (AGB), cancellation policy and privacy policy instead. With free offers, check carefully whether updates when laws change and liability in the event of warning letters are included. A legal texts subscription with an update service is the safer choice for most stores.

Can I ask customers who bought before I installed the app for a review afterwards?

Technically yes, many apps can email older orders. Legally, however, you need consent or the existing-customer exception with a notice of the right to object. If both are missing, the email is unlawful advertising. An insert in future parcels is no solution for past customers, but it is for new orders.

How do I show all reviews together on the homepage?

Most review apps come with their own section for the theme editor, such as a carousel or a review wall with all reviews. You add it to the homepage. Remember that the notice about authenticity checks must also be visible there, directly on the section and not just on the product page.

May I delete negative reviews?

Only for objective reasons, such as insults, spam, personal data or content unrelated to the product. Criticism of quality or delivery time is part of it and should stay. Respond factually and publicly instead. That shows future customers how you deal with problems.

Do I also have to disclose checks for embedded Google reviews?

You should assume so. § 5b(3) UWG is triggered by making reviews accessible, and according to widespread opinion, embedded third-party content is not exempt. If you show Google reviews on your site, state next to them whether and how they are checked. With Google, you usually can't ensure that only buyers leave reviews, and you should say so.
